The more Facebook friends you have, the bigger your brain is
We know that Google makes us stupid - and can affect the way we remember information. But when it comes to social media popularity, the size of your brain matters.
Scientists at the University College London used brain scans to understand how Facebook and brain structure are related and found that the number of Facebook friends is linked to the size of certain brain regions. This may explain why some people have a few hundred friends online while other have thousands of friends on Facebook.
The scientists also found that the number of friends people had online, usually meant they had more friends off-line.

It's a known fact that Einstein's brain was only about the size of a walnut. People could actually hear it sloshing around when he wrote on a chalk board. That's why he had such big hair: winter insulation.
